CD43 Antibody (MA5-16339) in ICC/IF
Immunofluorescence analysis of CD43 was performed using 70% confluent log phase U-937 and HT-29 cells. The cells were fixed with 4% paraformaldehyde for 10 minutes, permeabilized with 0.1% Triton™ X-100 for 15 minutes, and blocked with 2% BSA for 1 hour at room temperature. The cells were labeled with CD43 Monoclonal Antibody (SP55) (Product # MA5-16339) at 1:100 dilution in 0.1% BSA, incubated at 4 degree celsius overnight and then with Goat anti-Rabbit IgG (Heavy Chain), Superclonal™ Recombinant Secondary Antibody, Alexa Fluor 488 conjug...

Product Specific Information
Heat-mediated antigen retrieval is recommended prior to staining, using a 10mM citrate buffer, pH 6.0, for 10 minutes followed by cooling at room temperature for 20 min. Following antigen retrieval, incubate samples with primary antibody for 30 min at room temperature. A suggested positive control is tonsil tissue.
Target Information
CD43 (leukosialin, sialophorin) is a transmembrane mucin-like protein with high negative charge, expressed on the surface of most hematopoietic cells. CD43 contributes to a repulsive barrier that interferes with cellular adhesion, however, in certain cases also promotes leukocyte aggregation. By interaction with actin-binding proteins ezrin and moesin CD43 plays a regulatory role in remodeling T-cell morphology and regulates cell-cell interactions during lymphocyte traffic. CD43 signaling both enhances LFA-1 adhesiveness and counteracts LFA-1 induction via other receptors. Expression of CD43 causes induction of functionally active tumor suppressor p53 protein, but in case of p53 and ARF deficiency CD43 promotes tumor proliferation and viability. CD43 appears to be an important modulator of leukocyte functions. Diseases associated with CD43 dysfunction include Wiscott-Aldrich Syndrome and Adenoid Basal Cell Carcinoma.
